My question then is, as long as there is a double QE and honey frame > barrier (say 10) between the queens will the bees from the two colonies > allow the queens to coexist or will they eventually kill one of the queens? I've successfully overwintered two queens in a single, divided by a vertical plywood divider board, covered by an excluder, with a shared box of honey above. The workers have the ability to readily pass between the two queens' brood chambers. I observed good queen survival in the ten test hives. And yes, the question always is whether the benefit is worth the hassle.
